I just can't bring myself to think spending $1600 for a gaming graphics card makes sense, and despite rebrands to now a "90" class, to me these are no different then what a 1080 Ti or 2080 Ti were to their respective generations and product stacks for much cheaper. The cost of the cards are not explained by only increased wafer costs or inflation when we see Nvidia is making more money then they ever have with bigger margins then ever. Something doesn't track with that narrative.
I'm also highly concerned about 500W or more going through a single part when my 350W 3080 Ti already acts like such a space heater during a gaming session. That said, despite the larger overall power draw vs the 3090, the improvements in the 4nm (refined TSMC 5nm) is clear. Samsung 8nm was just a refined 10nm which made it quite ancient by comparison. That said, just that transistor density increase is crazy! I will be curious to see how the increase in L2 cache looks for the 4080 and 4070 in the future with their 256-bit and 192-bit buses.
All that said, can't argue with the impressive results and this is clearly the card for 4k120. I am also on a 48" C1 OLED, and when I honestly sit down and think about it, it takes me forever to get around to playing modern games. I am only now playing Control and have yet to ever fire up CP2077. At this point, I am content with what I have and will look forward to seeing what a future 50-series or RDNA4 (or whatever it ends up being) and seeing what the card that can do 4k120 in those product stack looks like in cost and power. Hopefully both will be much lower.
I do really look forward to what you can do with this puppy under water though!
